MCC USB-231: 16-bit 50 kS/s Multifunction USB DAQ Device

The Measurement Computing USB-231 is a USB-based, 16-bit, multifunction DAQ devices. It features 8 SE/4 DIFF analog inputs, with a fixed analog input range of ±10 V, 16-bit resolution, two 16-bit analog outputs, eight digital I/O, one 32-bit counter, and a 50 kS/s sample rate. The USB-234 features a 100 kS/s sample rate. It is USB-powered and require no external power.

There are two 16-bit analog outputs. One or both outputs can be updated at a rate up to 5 kS/s per channel. The output range is fixed at ±10 V.

Eight TTL-level digital I/O lines are included with USB-230 Series devices. Each channel is software-selectable for input or output. Digital input voltage ranges from 0 V to 5 V are supported, with thresholds of 0.8 V (low) and 2.3 V (high). When used in output mode, each digital channel allows for 3.3 V operation with a source/sink current limit of±ñ4 mA. All DIO lines are set to high-impedance inputs at system startup and reset. The device does not drive the signal high or low. Each line has a weak pull-down resistor connected to it. All digital I/O updates and samples are software-paced.

USB-230 Series devices include an external digital trigger input that is software selectable for rising edge or falling edge detection, and they support one 32-bit edge counter (rising) that accepts inputs up to 5 MHz.

Software support includes DAQami, an optional out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages including Visual C++®, Visual C#®, Visual Basic®.NET, DASYLab®, LabVIEW™, MATLAB®, and Python™.
